Dentists Spent the Last Three Months Testing the Best Selling At-Home Teeth Whitening Kits!

These are the top 5 at-home teeth whitening kits for anyone looking to achieve a brighter, whiter smile in just a week.

After experiencing the many pitfalls of teeth staining (from plaque build up, coffee, wine, aging, and more), we started exploring alternative whitening methods this season. Since professional whitening treatments aren’t the most time-friendly option (appointments can take up to an hour and cost upwards of $500 per session), and some of us can’t make it to the dentist right now, we’re looking at the next best thing: at-home teeth whitening kits.


But here’s the catch, most teeth whitening kits can cause extreme sensitivity, which can make the process uncomfortable and even painful for many people. That’s why we focused on finding options that are not only effective but also gentle enough to protect enamel and minimize sensitivity.


As a certified dental professional with many years in the field, I was lucky enough to combine my love for dental care and science to discover which at-home whitening kits really work, and which are just another overhyped disappointment.

We tested 24 at-home teeth whitening kits, including models from HiSmile, Snow, Novashine, and Puur Smile. We rated the best five options based on the following criteria:

Results


We tested how many shades whiter our teeth became over a week of consistent use. A few of the kits worked exceptionally well, delivering visibly brighter smiles while protecting enamel strength.

Cost


If you were to go the in-office route, a professional teeth whitening session could cost up to $500 per treatment, with multiple sessions often needed for full results. We were able to achieve impressive whitening results with kits costing well under $500, with the best-performing option priced at just around $99*

Safe for At-Home Use


New York-based dentist Dr. Emily Harrison considers at-home teeth whitening kits a safe alternative. "Whitening solutions work by using peroxide-based ingredients to break down stains on the enamel,” Dr. Harrison explains. “When formulated correctly, these treatments can effectively brighten teeth without harming the enamel." We focused on finding at-home solutions with gentle, non-toxic formulas designed to protect enamel health while delivering professional-grade whitening results.


We looked for the teeth whitening kits on the market that brighten teeth effectively and are safe for at-home use.

    I've tried the Puur Smile Kit, it works wonders! My teeth are already several shades whiter.

    How does this work? Does it use a similar light as the one at the dentist? I used to go for in-office whitening but it was so pricey!

    In-office whitening is fast, but Puur Smile and similar at-home kits really make a difference too. You just need to use it consistently.
